Problems solved by technology

The selenium-enriched chrysanthemum after selenium-enriched culture is not only delicious, but also has the function of strengthening the body's selenium element. However, the current selenium-enriched mushroom cultivation technology still has the disadvantages of slow growth of edible fungus, low selenium-enriched amount, and selenium-tolerant ability. Weakness and other issues

Embodiment

[0017] Cultivation of test-tube strains: insert Pleurotus erodes strains into PDA medium to prepare test-tube strains;

[0018] Plate seed culture: Take a small piece of test tube seed and insert it into a plate filled with sterilized PDA-enriched medium, and place it in a constant temperature incubator at 25°C for cultivation until the hyphae cover the surface of the plate medium.

[0019] Liquid mother seed culture: Take five 0.8cm-diameter petri dishes and insert them into the Erlenmeyer culture flask filled with sterilized PDB-enriched medium; the shaking submerged culture conditions are: 25°C±0.5, rotating speed 150±2r / min.

[0020] Selenium-enriched mycelia culture: Inoculate the mother seed with 10% liquid seed quantity in a triangular culture flask equipped with sterilized PDB plus selenium-enriched medium, and the shaking deep layer culture conditions are: 25°C±0.5, rotating speed 150±2r / min.

[0021] Preparation of selenium-enriched chrysanthemum mushroom powder: s...

Abstract

The invention relates to a method for preparing selenium-abundant mushroom powder. Wherein, it plants the mushroom seed into PDA culture medium to cultivate seed in tube; plants tube seed into PDA selenium-abundant culture medium to process solid product seed cultivation; cultivating the solid product seed in PDB selenium-abundant container to process solid mother cultivation; plants liquid mother into PDB selenium-abundant culture medium to process selenium-abundant little mushroom cultivation; separates the selenium-abundant little mushroom from culture medium; drying and breaking into powder. The invention has high culture speed and low material consumption. And the product has high organic selenium convert ability, and high selenium content.

Description

technical field [0001] The invention relates to edible fungus liquid culture and culture medium formula, and more specifically relates to a preparation method of selenium-enriched pear mushroom powder. Background technique [0002] In recent years, my country's edible fungus technology has developed rapidly, especially the cultivation technology of selenium-enriched mushrooms, such as the cultivation of selenium-enriched shiitake mushrooms (Ye Huafu, publication number cN1213488A, "Selenium-enriched shiitake mushroom additives"). Selenium is an essential nutritional trace element for the human body. It participates in some important metabolic processes in human tissues, and has the function of regulating the proliferation and differentiation of cancer cells and reversing the malignant phenotype. Selenium enrichment technology of edible fungi uses the intermediate products of the metabolic transformation of edible fungi as the carrier, adds selenium for biological enhancement...
